Description

Falling into the water

This invention is a drain head, especially a drain head structure that can achieve drainage and sealing effects at the same time, and is anti-odor and insect-proof.

According to the current situation, a drain head is installed on the drainage hole of the floor in places that require water washing. The structure of the existing drain head is mainly composed of a drain head base and a cover plate. The drain head base has A simple groove, the drain head base is provided with a drain hole at the bottom, and the cover plate is provided with a plurality of hollow drainage holes, whereby the drainage holes of the cover plate are used to allow sewage to flow through the drain holes of the cover plate. It is discharged into the drain pipe through the drain hole of the drain head seat. At the same time, the blocking of the cover plate can appropriately block foreign matter, so that foreign matter will not flow into the drain pipe and cause obstruction.

However, it was found that since there is no shielding or separation between the cover plate of the drain head and the drain hole of the drain head base, the odor of the drain pipe will be directly transmitted to the drain pipe from the drain hole of the drain head base and the drain hole of the cover plate. Indoors, pests such as cockroaches, mosquitoes, centipedes, etc. will also enter the room through this route, which will affect environmental hygiene and cause discomfort to personnel due to odor.

In order to solve the above problems, some manufacturers have developed a drain head that is odor-proof and insect-proof. The main method is to install a blocking plate on the drain head base, so that the blocking plate can be kept covered and closed when there is no drainage. The state of the drain hole prevents pests or odors in the drain pipe from entering the room. When draining, the power of the water flow can be used to directly open the blocking plate to achieve the function of sewage discharge.

However, because the above-mentioned drain head has many components, is complex in structure, and has a high cost, and when the blocking plate is stuck by hair, dirt or foreign matter to form an opening gap, it cannot reliably cover and seal the drain hole, which makes pests Odors and odors can still enter the room through the opening gap; therefore, in addition to having a high preparation cost, this type of drain head with a blocking plate also has the disadvantage of being unable to reliably prevent odors and insects.

The purpose of this invention is to improve the above-mentioned shortcomings and provide a drainage head structure that can simultaneously achieve drainage and sealing effects, and is anti-odor and insect-proof.

In order to achieve the above purpose, the water drop head of this invention includes a drainage seat and a water holding seat; among them: the drainage seat is made of one piece, the drainage seat is generally in the shape of a tube, and the outer periphery of the opening on the drainage seat is The expanded ring is provided with abutment edge, the bottom of the drainage seat is formed with a stop rib, the center of the stop rib has a first positioning portion, and the bottom of the drainage seat forms drainage holes on both sides of the stop rib; the water holding seat has a It is made of one piece and has a water-holding space. A protruding column is formed in the center of the bottom surface of the water-containing space. A second positioning part is formed on the protruding column. The second positioning part is connected with the first positioning part of the drainage seat. It can be combined correspondingly, so that the water-holding seat can be combined with the bottom of the drainage seat, and the drainage hole of the drainage seat extends into the water-holding space, and the top surface of the water-holding seat and the bottom surface of the abutment edge of the drainage seat form a gap. ; Through the above structure, a drainage head structure can be provided that can simultaneously achieve drainage and sealing effects, and is anti-odor and insect-proof.
